Sure. The two most popular examples are the C Plus Equality repo and the Operation Disrespectful Nod repo, which were a satirical programming language and a Gamergate resource list for contacting advertisers, respectively.
It's not proof that _he_ necessarily removed it, but considering it wasn't brought down by the actual repo maintainer, and that any repos created to replace it by other users at the time were taken down as well, it's a safe assumption that someone at GH did.
There's several more sources regarding this, but I'm on a terrible mobile connection at the moment. Googling around will get you a bit more info for the story.
This is an impressive pain in the ass. I race too and the only lock its ever trusted behind is a deadbolt. I bought a very nice mid 80s road bike for my commuter because its about as light as an entry level race bike but looks like nothing special.
If you really care, get the fancier lock (Kryptonite Fuhgettaboutit (http://www.amazon.com/Kryptonite-997986-Black-Fahgettaboudit...) they recommend and buy locking skewers. Then don't buy a new bike, but get a mid-80s steel bike and call it a day. I've left bikes locked up in the worst neighborhoods in SF overnight and haven't had shit stolen.
You were able to hail a cab in the street? Lucky you. I've had cabbies refuse to take me to where I want to go. I've called cab companies, told them where I am, and they refuse to come pick me up. I've seen a cab turn down an elderly couple want to go across town because his "meter was broken", but 2 minutes later take a fare that just went a couple blocks. And I'm a white male. Minorities have an even harder problem getting cabs.
Depending on where you live, cabs are not always something that is just as easy or reliable as Uber/Lyft/Sidecar/etc. When I'm unable to get home for whatever reason, I need a service I can rely on.
Personal anecdote here, but I don't look like I belong in the loop for anything other than begging. I'm an overweight white male with long, typically unkempt hair, an untrimmed beard, and a pair of shoes that are dirty and have an obvious rip in the front. My jacket is dirty and often covered in mud / dust / etc. Most of the beggars I pass on my walk into work look far better off than I do.
I have never felt as though I couldn't get a cab in Chicago. Not during rush hour in the loop (when I could easily be passed for a well-off guy in a suit thirty paces down the line). Not at 3am when the bar is closing and there exists a line of upper middle class to upper class drunks failing over themselves for a cab. Not on Michigan at lunch. Endless opportunities to not pick up a ragged homeless guy, and money always plays.
Do you have any source on that?
